The dimensionalities of these two components always sum to ''n'', and they represent the ''space'' and ''antispace'' associated with the object. (Antispace is also known as negative space or counterspa..."

That post introduces the geometric antiproduct and the notation $$\unicode{x27D1}$$ and $$\unicode{x27C7}$$ used in this post. As before, everything in this post assumes familiarity with Chapter 4 of FGED1. I have been thinking about the geometric product and geometric antiproduct on a low-priority thread for most..."

The second part can be found here: Symmetries in Projective Geometric Algebra. In the last chapter of FGED1, I provided a practical introduction to projective Grassmann algebra. Most people working in computer graphics are familiar with four-dimensional homogeneous coordinates, and projective Grassmann algebra extends this concept to a larger algebraic structure under which the wedge and antiwedge products per..."
